Method for ventilating a motor

Abstract

Certain exemplary embodiments comprise a system comprising: a motor stator comprising: a motor frame comprising a core shell adapted to surround a stator core comprising: a plurality of panels; a plurality of apertures located in one or more of said panels; and a first plurality of non-destructively removable plates adapted to effect a first direction of stator core air flow by impeding airflow through a first selectable sub-plurality of said plurality of apertures.

1. A method for cooling a motor, said method comprising a plurality of activities comprising:
 operating a motor that defines a longitudinal axis, the motor comprising a stator core surrounded by a core shell, the core shell comprising:
 at least four longitudinal panels; 
 a plurality apertures located in one or more of the at least four longitudinal panels, the plurality of apertures adapted to be covered by a plurality of non-destructively removable plates adapted to, said plurality of plates adapted to change ventilation of the motor from an X ventilation scheme to a Z ventilation scheme, the X ventilation scheme comprising cooling air entering the motor from both longitudinal ends of the motor, flowing parallel to a longitudinal co-axis of, and between, the rotor and stator, radially through the stator, and substantially exiting via one or more apertures in the core shell, the Z ventilation scheme comprising cooling air entering the motor from a first longitudinal end, flowing axially and parallel to a longitudinal co-axis of, and between, the rotor and stator, and substantially exiting via a second longitudinal end on an opposing end of the motor from the first longitudinal end; and 
 
 covering a first selected sub-plurality of said plurality of apertures with a first sub-plurality of said plurality of non-destructively removable plates. 
 
     
     
       2. The method of  claim 1 , further comprising:
 removing the first sub-plurality of non-destructively removable plates from the first selected sub-plurality of apertures. 
 
     
     
       3. The method of  claim 1 , further comprising:
 relocating the first sub-plurality of non-destructively removable plates to a second selected sub-plurality of apertures. 
 
     
     
       4. The method of  claim 1 , further comprising:
 covering a second selected sub-plurality of apertures. 
 
     
     
       5. The method of  claim 1 , further comprising:
 covering a second selected sub-plurality of apertures with a second sub-plurality of non-destructively removable plates adapted to effect a second direction of air flow across the stator core. 
 
     
     
       6. The method of  claim 1 , further comprising:
 circulating air along the stator core of the motor. 
 
     
     
       7. The method of  claim 1 , further comprising:
 operating a fan attached to a rotor of the motor. 
 
     
     
       8. The method of  claim 1 , further comprising:
 operating a fan attached to a rotor of the motor, the fan adapted to circulate air along the stator core of the motor. 
 
     
     
       9. The method of  claim 1 , further comprising:
 effecting air flow within the care shell. 
 
     
     
       10. The method of  claim 1 , further comprising:
 adjusting a baffle coupled to the core shell, the baffle adapted to effect stator core air flow. 
 
     
     
       11. The method of  claim 1 , further comprising:
 adjusting a baffle comprised by the motor, the baffle adapted to effect stator core air flow. 
 
     
     
       12. The method of  claim 1 , further comprising:
 causing stator care cooling air to flaw across a heat exchanger. 
 
     
     
       13. The method of  claim 1 , wherein:
 the care shell comprises at least six longitudinal panels. 
 
     
     
       14. The method of  claim 1 , wherein:
 the core shell comprises at least eight longitudinal panels. 
 
     
     
       15. The method of  claim 1 , wherein:
 each of the at least four longitudinal panels has a longitudinal dimension, the plurality of longitudinal dimensions of the at least four longitudinal panels being substantially equal. 
 
     
     
       16. The method of  claim 1 , wherein:
 the at least four longitudinal panels define a regular polygon. 
 
     
     
       17. The method of  claim 1 , wherein:
 a configuration of the motor qualifies as a National Electrical Manufacturers Association weather protected enclosure. 
 
     
     
       18. The method of  claim 1 , wherein:
 a configuration of the motor qualifies the motor as a National Electrical Manufacturers Association weather protected motor. 
 
     
     
       19. The method of  claim 1 , wherein:
 a configuration of the motor qualifies the motor as a Totally Enclosed Air-to-Air Cooled motor. 
 
     
     
       20. The method of  claim 1 , wherein:
 a configuration of the motor qualifies the motor as a Totally Enclosed Water-to-Air Cooled motor.
